TYP EWRI 'IING MACHINE.

Application filed. January 16, 1922.. Serial No. 529,415;

To all whom it may concern: v I

Be it known that I, GEORGE A. SEIB, citizen of the United States, andresident of llion, in the county of Herkimer and State of New York, haveinvented certain new and useful Improvements in Typewriting Machines, ofwhich the following is a specification.

My invention relates to typewriting machines and more particularly toaccent writing or dead key mechanism for such machines. I

The main object of the invention, generally stated, is to providesimple, inexpensive and eflicient means of the character specified.

A further object of the invention is to so combine such mechanism withpolychrome ribbon mechanism that either color or field of ribbon broughtinto use according to the setting of said ribbon mechanism, will bepresented to the printing point at the actuation of an accent writing ordead key type action, as well as at an actuation of an ordinary typeaction. I

A still further object of my invention is to provide means of thecharacter specified above, which in the main is in the nature of anattachment that may readily be incorporated in existing typewritingmachines without, modifying, or materially modifying, the structuralfeatures of said machines as they now exist.

To the above and other ends which will hereinafter appear my inventionconsists in the features of construction, arrangements of parts andcombinations of devices set forth in the following specification andparticularly pointedi out in the appended claims.

In the accompanying drawings wherein like reference characters indicatecor-- responding parts in the various views,-

I have shown my invention embodied in the present instance in aRemington portable machine, which is somewhat like that shown forexample in the patent to Joseph B. Holden, No. 1,397,166, dated November15, 1921, and in which the invention may be readily incorporated withoutmodifying, or materially modifying, the structural features of saidmachine in effecting such incorporation. It should be understood howeverthat the invention is not restricted to use in a machine of this stylebut may be employed wherever found available.

The means employed in the Remington portable machine for actuating theribbon vibrator from the universal bar, and for controlling its actionfor polychrome work, is much like that shown in the above mentionedHolden patent, and this construction is employed with very slightmodifications in the present construction, as will hereinafter appear. I

Referring first to the general construction of the machine, the mainvouter sheet metal frame 1 contains an inner sheet metal frame 2 securedthereto, and which supports various working parts of the machine. A typebar segment 3 is supported by the frame 2, and is slotted to receive theheels of type bars pivoted to the segment at 4 and striking rearwardlyand downwardly against the top of a platen 5. I have represented onlthree of the type'ibars and their associmeral 6 represents one of theordinary type bars at about the center of the system where as thereference numerals 7 and 8 indicate two type bars at the right-hand sideof the system which carry types for writing accent marks in both upperand lower case. The ordinary type bar 6 may strike at a common printingcenter and if desired the accent types may print above or below saidcenter. In such a case the accent mark is written first and thecharacter to be accented is written afterwards. I prefer, however, tooffset the type blocks carrying the accent marks so as to print oneletter space to the left of the common printin center, as disclosed inmy application, br. No. 476,768, filed June 11, 1921. By such aconstruction the character to be accented may be written first and theaccent afterwards added above or below the writtencharacter with the aidof a dead key, as pointed out in said application. All of the type bars6, 7 and 8 may be mounted in guide slots that radiate from a commoncenter, as is commonly the case. I prefer, however, to mount the accenttype bars 7 and 8 in non-radial slotsas disclosed in my said previouslyfiled application. Since however this feature, as well as theoff-setting of the accent type blocks pointed out above, are claimed inmy said application and are not claimed herein, I make no specificshowing of these features in this case.

In the present construction each of the type bars has its heel formedwith segmentally arranged teeth' '9 which mesh with similar teeth 10 ona sub-lever 11. These sub-levers are pivoted at 12 on a slotted support13 carried by the fixed supporting frame 2 of the machine. The forwardend of each sub-lever 11 is pivoted at 14 to a depending link 15, whichin turn is pivoted at its lower end, as at 16, to a sub-lever 17fulcrumed at 18 on a combined fulcrum and comb plate 19. Each lever17also is pivoted at 20 to a depending link 21 pivoted at its lower end,at 22, to a key lever 23, 24 or 25 provided with a finger key. Thefinger key for the lever 23 is designated by the reference numeral 26,and those for the levers 24 and 25 are indicated by the referencenumerals 27 and 28 respectively. The links 21 for the ordinary, ornon-dead key, type bars 6 are connected to the key lever 23 and othersimilar key levers, whereas the links 21 for the dead key type bars 7and 8 are connected respectively to the key levers 25 and 24.

It is intended in the present instance to mount the platen 5 in acarriage which is supported for bodily case shifting movementfore-and-aft of the machine, to bring either of the types29 and 30 intouse, as in the I Remington portable machine, and as illustrated in thepatent to Joseph B. Holden,

panying drawings but may be of any suitable character, such as thoseempoyed in the Remington portable machine, or such as those disclosed insaid patent to Holden, No. 1,386,256. It is also intended in the presentinstance to effect a movement of the universal bar frame together withsome of the parts associated therewith, as in the Remington portablemachine, and somewhat in the manner disclosed in the patent to J o sephB. Holden, No. 1,347,632, dated July 27, 1920, and such constructionwill now be described.

The case shift frame comprises sheet metal side plates 31 that extendfore-and-aft of the machine and are pivotally connected at their forwardends, as at 31 to depending links 32, pivoted on inwardly projectingpins 33 on the fixed frame 2 of the machine, and prevented fromaccidental detachment therefrom by cotter pins 34. The rear end portionof each side plate is bent inwardly to form a supporting piece or flange35, to which a carriage support or casting 36 is detachably secured byscrews 37. The member 36 constitutes a part of the shift frame and ispivoted at 38 to upright arms 39 fixed on a rock shaft 40, pivoted atits ends to the frame 2 of the machine. The carriage supported bycasting 36, together with other parts mounted on or supported by thecase shift frame, are thus adapted to receive a movement with said framefore-and-aft of the machine on the arms 39 and links 32, springs 4Otending to return the shift frame to normal osition. Among the partsthus shifted with the shift frame is the universal bar frame and partscarried thereby, as well as the dog rocker 41, and a feed rack 41 carried by the carriage. These parts therefore maintain the same relationin either case position to which the shift frame may be moved. sheetmetal lever-like side plates 42, pivoted at 43 to the side plates 31 ofthe shift frame. As shown at the right-hand side of Fig. 2 the head ofeach pivot screw 43 has a pivotal bearing in a side plate 31, each screwbeing held against detachment from the universal bar frame by a nut 44.The rear end 45 of each plate 42 coacts with an extension or stop 46 onthe associated flange 35 of the shift frame, to limit the returnmovement of the universal bar frame on its pivots 43 under the action ofreturning springs 47. Each of these springs is connected at one end at48 to the side bar or plate 42 of the universal bar frame, and at itsopposite end to a laterally projecting pin 49 extending from the sidebar or plate 31 of the shift frame. Each side plate 42 The universal barframe comprises i is provided with an inwardly extending flange 50 towhich is riveted a sheet metal cross bar 51, to rigidly connect the sideplates 42. The cross bar 51 is bent into sub stantially U-shapedformation in cross-section throughout most of its length, to givegreaterrigidity thereto. Each side plate 42 also is provided with aninwardly extending flange 52 to which is riveted a sheet metal universalbar, designated as a whole by the reference numeral 53; said universalbar constituting a further tie between the side plates of the universalbar frame. This universal bar has upwardly and forwardly bent integralcontact devices or curved fingers 54, one arranged beneath each of thekey levers 23 of the non-dead key type actions. Those fingers 54 whichordinarily would be beneath the dead key levers 24 and 25 are broken offor detached. It follows that each of the key levers 23 of the ordinarytype actionsis effective'to actuate the universal bar, but the dead keylevers 24 and 25 are ineffective thereon. Secured to'the universal barby a screw 55 is a sheet metal combined connecting and actuating member,designated as a whole by the reference numeral 56. -As best shown inFig. 2 this member has "an off-set foot piece 57 secured by screws 58 onthe upper side of the cross bar 51. The member 56 also has a rearwardlyextending actuating arm 59 which carries a laterally projecting pin orcontact'60. This pin extends beneath an ear or contact 61 bent laterallyfrom an arm 62-formin'g part of the dog rocker 41. The latter is mountedto oscillate on pivot screws 63 threaded into tapped openings independing lugs on the casting 36 of the shift frame, the screws havinglock nut 65 to prevent accidental displacement thereof. It

I will be understood therefore that an opera.-

tion of any key lever 23 is efiective to move the universal bar, causingthe frame of the latter to be rocked and the dog rocker to be actuatedby the contacts 60 and 61, and a letter space movement of the carriageto beeifected. However, no such letter space movement of the carriagewill result from an actuation of either of the key levers 24 and 25 ofthe dead key type actions, although a printing of an accent mark will beeffected. v

Whether the key actuated be that of one of the ordinary type actions, asthe key 26, or that of one of the dead keys, as 27 or 28, itis necessaryto interpose the ribbon66 in the path of the approaching type at eachprinting operation. In the present instance the ribbon vibrator 67 ismounted on a fixed type guide 68 to slide fore-and-aft of the machine ina slightly inclined plane, to cover and uncover the printing point, andalso to shift with the case shift frame, as will hereinafter more fullyappear. The

type guide is secured'by screws 69 to the type bar segment '3, whereasthe ribbon vibrator is detachably connected a-t'i'O to a link 71, thelower end of whichv is pivoted at 72 to alever arm 73 of a vibratoractuating member, designated as a whole by the reference numeral 74. Themember 74 is made of sheet metal and'formed with a sec ond arm 75parallel for a portion of its length with the arm 73. A sheet metalbracket 7 6 is secured by screws;77 to the casting 36 of the shift frameand has perforated ears 78 which are received between theparallel arms73 and 75 of the member 74. A detachable pivot pin 79 extends throughopenings in the arms 73 and 75and ears 78, to pivotally support themember 74 on the bracket 76. A coiled returning spring 80 surroundsthe'pivot 79, and bears'at one end against the member 74 and at itsopposite end against the bracket 76. This spring ere erts its force toreturn the member 74, and the vibrator connected therewith, to normalposition after each actuation of the vibrator. The arms 73 and 75are.slotted to receive and permit a relative longitudinal movement of aso-called controlling wire or connecting member 81 to be effected. Thismember 81 constitutes 'an operative .connec-, tion between the universalbar frame and the member 7 4 for the transmission of movement from theformer to the latter. The slot in the arm 75 through which the wire 81passes is indicated at 82. The free end portion of the wire 81,'afterpassing through the slot in the arm 7 3 extends through a forked guide82 formed as a part of the arm 73 and effective to prevent adisplacement of the wire laterally in its slots. But said fork does notinterfere with the longitudinal adjustment of the wire from the positionshown in Fig. 2, to that indicated in Fig. 3, or vice versa. The wire 81is bent at 83 so as to provide two parallel engaging portions 84 and 85at-different distances. from the pivot 79 of the-vibrator actuatingmember 74, and at difi'erent distances from the pivotal center of theuniversal bar framei L. i 1

An actuating or lever arm 86 extends beneath the wire 81 between theparallel portions of the arms 73 and 75, and is formed a part of themember 56 secured'to the universal bar frame. At the actuation of ak'e'y lever 23 of an ordinary type action, the universal bar will bedepressed moving the arm 86 upward and operating thei vibratorthroughthe intermediate wire 81; The adjustment of the wire to the Fig. '2position brings the part 85 of the wire into co-opera tive relation withthe arm 86, and the leverage is' such that at this time'the vibratorwill be moved" by the arm 86 at each actuation of a key 26 adistancesufiicient to bring the upper part, or say the black field a, ofthe ribbon to the printing point. W hen,

STA

however the wire 81 is shifted to the Fig. position, the part 84 of thewire will be positioned for co-operation with the arm 86, thus changingthe leverage ratio of the parts by which the vibrator is actuated. Anoperation of the key 26 at this time effects a longer throw of thevibrator and brings the lower half, or say the red field b, of theribbon into use.

I have described how the ribbon vibrator is actuated from the universalbar at each operation of an ordinary printing key 26 whether the wire 81be set to write in one or the other of the two fields a and Z) of theribbon, and how the operation of the universal bar also brings about anoperation of the escapement mechanism. Since an operation of either ofthe dead keys 27 and 28 does not actuate the universal bar, it becomesnecessary to actuate the ribbon vibrator independentl thereof and it ispreferable, of course, to print the accent mark in the same color as thecharacter to be accented. Thus, if the writing is being done in red, itis desirable that the accent marks also be written in-red, whereas, ifthe writing is being done in black it is desirable that the accent marksbe printed in black. These results I accomplish by the special device orattachment of my invention co-operating with the parts hereinbeforedescribed in a manner which will now be set forth.

Referring first to Figs. 1 to 5 incluslve it will be seen that a sheetmetal bracket 87 is secured by screws 88 on top of cross bar 51 of theuniversal bar frame. This bracket has depending ears 89 that extend downin front of the cross bar 51, and are recessed in the rear edges thereofto form bearing openings 90 (see Fig. 5). These openings are closed atthe rear by the cross bar 51 and receive a wire rock shaft 91 therein.The outer end of the rock shaft is provided with a forwardly extendingintegral arm 92 which terminates in an inwardly directed extension 93.This extension projects be neath the dead key levers 24 and 25 in aposition to be actuated by each of said levers to rock the shaft 91. Theopposite end of the shaft is provided with a downwardly and rearwardlyextending integral arm 94 arranged at its rear end portion parallel withand adjacent to the actuating arm 86. Like the latter, the arm 94 cooperates with the wire 81 either at the part 85 or 84 thereof, dependingon the setting, or longitudinal adjustment, of the wire 2, write blackor red, as shown in Figs. 2 and 3 respectively. It will be understoodtherefore that a depression of either dead key lever will be ineffectiveon the universal bar, so that no movement of the carriage is effected.But the rock shaft 91 will be rocked by a dead key lever, therebyelevating the arm 94 while the universal bar and the racer-1e actuatingarm 86 connected therewith remain at rest, as shown in Fig. 5. Thisresults in moving part 85 of the member 81 from the dotted to the fullline position in Fig. 5, assuming that the parts are set so that the arm94 coacts with the section 85 of the member 81 as shown. The arm 94 atthis time moves the ribbon vibrator to bring the black field a of theribbon to the printing point, exactly as such movement of the vibratoris effected by the actuating arm 86. The ribbon vibrator is given agreater or less extent of throw by the arm 94 depending upon the settingof the polychrome mechanism, or the wire controlling devices 81, towrite red or black, the difference in throw being effected by thevariable leverage mechanism in the manner set forth.

In Figs. 6 and 7 I have shown a slightly modified form of vibratoractuating oscillating device controlled by the dead keys. Theconstruction shown in these views is intended for employment moreparticularly where type actions at different parts of the system are tobe selected for accent writing or dead key construction. Where one ormore type actions at an end of the system are to be employed as dead keytype actions,

I prefer to employ the construction shown in Figs. 1 to 5 inclusive, butwhen a selection is to be made at will, or one or more intermediateactions are to be used for accent writing, then the constructiondisclosed in Figs. 6 and 7 lends itself more readily to employment inthe machine. Thus referring to Figs. 6 and 7 it will be seen thatI-provide a rock shaft 95, corresponding to the rock shaft 91, andmounted like the latter to turn in bearings in a sheet metal bracket 96secured by screws 97 to the cross bar 51 of the universal bar frame. Anarm 98 extends from this rock shaft, and like the arm 94 in thepreviously described construction, coacts in the same manner with thewire 81 to shift the ribbon vibrator. Intermediate of its ends the rockshaft is flattened at. 99 and has a sheet metal platelOO welded orotherwise fixedly secured thereto. Assume that the plate 100 is firstmade like that shown in Fig. 7 with a number of adjacent contacts ortongues 101 corresponding in position to a number of adjacent keylevers, eleven such tongues or contacts being shown in Fig. 7. Whenmounted in the machine one of these contacts would extend beneath eachof the first eleven key levers at the right-hand side of the machine.Any one or more of these eleven type actions may be selected for use asan accent'wri-ting or dead key type action. In the example shown in Fig.6 I have selected the first (from the right) andthe fourth type actionsfor use as dead key actions. This requires that all oi the contacts 101except those which are to stand beneath the first and fourth key levers102, 103 respectively be out or broken off, and that the correspondingcontacts 54 of the universal bar which lie beneath said key levers bebroken or cut off, whereas all of the remaining contacts 54 "for theordinary key levers 23 remain intact for co-operation therewith. In thismanner any one or more of the first eleven type actions from the rightmay be selected for use as dead key type actions.

Any suitable means may be employed for adjusting the wire 81longitudinally to either of the set positions shown in Figs. 2 and 3.

' In the present instance I show the means employed in the Remingtonportable machine, and which comprise a sheet metal bell crank lever 104formed with an upwardly extending fork 105. The wire 81 near itsrighthand end, is bent to provide a section 106 which extendsfore-and-aft of the machine and passes through the fork 105. From thispoint the wire extends to the right where it forms a section 107 thatextends througha guide opening in a guide or bracket 108 secured to theright-hand flange 35 of the shift frame. The guide 108 aids insupporting the wire member 81, and in guiding it in its longitudinaladjustment. The bell crank 104 is pivoted at 109 on a bracket 110secured by screws 110 to the right-hand side plate of the frame 2. A rod111 is connected at its rear end to the bell crank 104, and at itsforward end to a lever 112 pivoted at 113 on a bracket 114 that issecured to the righthand side plate of the frame 2. The bracket 114 isformed with a guide slot through which the upper end portionof the lever112 passes, and with detent means therefor, and also is provided withsuitable indicating means. The upper end of the lever 112 forms a fingerpiece 115 by which it may be shifted forward and back to move the wiremember 81 longitudinally to either the Fig. 2 or Fig. 3 position.

It will be understood that during a case shifting movement of the partsthe wire member 81 shifts with the case shift frame, the section 106 ofsaid member at this time slidin fore-and-aft of the machine in the fork105 of the bell crank 104. The latter,

however, remains in operative connection with the member 81 to adjust itin a like manner irrespective of the position to which the member 81 maybe shifted with the shift frame.

It also will be understood'that the carriag'e, feed rack, dog rocker,universal bar,

ribbon vibrator and actuating means therefor including the rock shaft 91(or 95), actuating members 86 and 74, and the controlling member 81 allmove together fore-andaft of the machine with the case shift frame anddo not have their relations altered by case shift movement of thelatter. By shifting the member 91 (or 95) and. the parts car= riedthereby, withthe shift frame and correlated parts in the mannerdescribed, I am enabled, by very simple means which in the main is inthe nature of an attachment, to readily embody in the Remington portablemachine, simple and highly efficient dead key mechanism withoutmaterially modifying the structural features thereof, as they now exist.Moreover-,the simple addition of the rock shaft 91 (or 95 as anattachment, avoids bringing about undue complications in the mechanismof the machine, in which the parts are already compactly arranged andconfined within a small space, addsbut little weight to the machine, andenables the dead key mechanism to be readily added to existing machines.1 K
